Explanation:
What holds base pairs together? a pairs of double-ringed nucleotides b sugar-phosphate backbones c hydrogen bonds d nitrogen-carbon bonds
In DNA, base pairs are held together by hydrogen bonds. Adenine and thymine are connected by two hydrogen bonds, while cytosine and guanine are connected by three. Sugar-phosphate backbones and nitrogen-carbon bonds do not hold the base pairs together.
Explanation:In DNA, base pairs which consist of double-ringed nucleotides, are held together by hydrogen bonds. The base pairs adenine (A) and thymine (T) are held together by two hydrogen bonds, while the base pairs cytosine (C) and guanine (G) are connected by three hydrogen bonds. These hydrogen bonds allow these base pairs to hold together, providing DNA its double helix structure.
It should be noted that sugar-phosphate backbones form the outer sides of the DNA helix but do not hold the base pairs together.
Similarly, nitrogen-carbon bonds are present in the bases and the sugar molecule but these are not responsible for the bonding of the base pairs. They exist in the individual nucleotides and not in the double-ring structure formed by base pairs.

Why did the development of vascular systems help plants move to land
Answer:
During evolution, plants have acquired a vascular system, which has greatly contributed to the success of land plants. The vascular system allows plants to rapidly transport water and nutrients over long distances between roots, growing deeply in soil, and shoots, growing upward toward the sun.
Answer:
It made it possible to move water within the plant structure.
Explanation:
The evolution of plants occurred, mainly, after atmospheric changes due to the release of oxygen by autotrophic organisms. Thus, the first species to colonize the terrestrial environment were bryophytes and mosses, and the main characteristic that facilitated colonization after the formation of multicellular organisms was the formation of epidermal tissue and structures that guaranteed protection against water loss, the movement of water within the plant.
In the Paleozoic period, the first plants with vascular systems emerged, which developed from the first plant groups that colonized the terrestrial environment. The vascular system is composed of xylem and phloem which are the vessels that conduct nutrients and water within the plant.
About 400 million years ago, ancestral plants went through several events of adaptive irradiation, and diversified into the different species that we know today. These adaptive events were fundamental for the colonization of the terrestrial environment, so that diverse environments with adverse conditions were colonized by the plants.
After the appearance of sap-carrying vessels, plants evolved and tall species emerged that constituted the first forests, even at the end of the Devonian period.
Most of the plants survived the extinction events of the Triassic period, however, the environmental and atmospheric changes may have caused more evolutionary events, mainly in relation to the formation of flowers and fruits, which exponentially increased the biodiversity of terrestrial flora from the period Cretaceous.
In addition to the morphological and physiological changes over evolutionary events, another important process in the evolution of plants is reproduction and, indirectly, dependence on water for this process.

What absorbs more carbon dioxide the atmosphere or oceans?
The oceans absorb more carbon dioxide than the atmosphere.
Explanation:
Oceans are absorbers of atmospheric carbon dioxide. Like in the terrestrial environment ocean animals take in oxygen and release carbon dioxide and ocean plants perform photosynthesis by absorbing carbon dioxide and releases oxygen.
Various human activities like burning of fossil fuels and several industrial activities cause the release of carbon dioxide in large amounts into the atmosphere which harms the earth and its inhabitants.
About one-fourth of the carbon dioxide produced in the atmosphere is absorbed by the oceans of the earth. Oceans are the carbon sink of earth. Absorption of carbon dioxide makes the ocean acidic which causes harm to several ocean beings.

a student wants to develop a model demonstrating how transplants can save lifes. The group of tissues that removes wastes and toxic matter from the blood is diseased in a patient . What type of lifesaving transplant would the patient require ?
Answer:
b
Explanation:
A patient with diseased tissues that remove wastes and toxic matter from the blood would require a kidney transplant. Matching a donor is essential to prevent immune rejection, and scientists are exploring growing organs from the patient's own cells to avoid this issue.
The group of tissues that removes wastes and toxic matter from the blood is primarily the kidneys. When these tissues are diseased, the patient would typically require a kidney transplant to replace the failing kidneys. For an individual requiring a transplant, finding a matching donor is crucial to prevent tissue rejection. This is due to the immune system potentially destroying the donor cells, recognizing them as foreign. Patients receiving bone marrow transplants, for instance, must have their own diseased marrow destroyed beforehand, and then donor stem cells are intravenously infused. However, in the case of a kidney transplant, the procedure involves connecting a donated kidney to the recipient's blood vessels and leaving the diseased kidneys in place if they're not causing complications.
Dialysis is an alternative treatment that filters blood using a machine, but it is not a cure for kidney failure. For patients with end-stage kidney disease, a kidney transplant is the ideal alternative to long-term dialysis. The main obstacle with transplantation is finding a donor that matches the patient's human leukocyte antigens (HLAs), which are critical for reducing the risk of rejection.

This is the part of a biogeochemical cycle where nutrients are rapidly moving throughout the systole. The elements tend to only be here for a short period of time.
Answer:
Gaseous cycle
Explanation:
Gaseous cycle inclines to travel more frequently than the sedimentary ones. To adjust more steadily to the changes in the biosphere because of the large atmosphere reservoir. The buildup of carbon dioxide are soon dissipated by wind or taken up by the plants. The extraordinary disturbances i.e. global warming are more often than local disturbances which is wild fires and storm driven events. During the rock phase other salt deposits out as rock and sediment in shallow seas eventually to be weathered and can be recycled.
The question pertains to a stage in biogeochemical cycles where nutrients move rapidly; these cycles help maintain ecosystem health by keeping essential elements available.
The part of a biogeochemical cycle being described relates to a phase where nutrients are in a state of rapid movement and transition, typically referred to as the 'active' or 'main' cycle. In this stage, elements move swiftly through the ecosystem, being taken up by organisms, traveling through food webs, and also cycling through the physical environment, such as soil and water.
This rapid cycling ensures that essential elements remain available to support life. An example is the circulation of nitrogen, which can be rapidly integrated into biological systems through the process of nitrogen fixation and become part of the proteins and nucleic acids in living organisms.
These processes are a crucial part of maintaining ecosystem health because they regulate the availability of mineral nutrients. Through biogeochemical cycles, elements like carbon, nitrogen, and phosphorus are recycled and converted into forms that can be used by plants and other organisms. The efficient functioning of these cycles is essential for the productivity and sustainability of both terrestrial and aquatic ecosystems.Which of the following statements about stars is true?
